VPN threat protection vs. dedicated antivirus: Are VPNs really enough?

Many VPN providers are now offering additional security features such as malware detection, malicious link checkers, and ad blockers, alongside their primary function of encrypting internet traffic. Notable VPNs like NordVPN and Surfshark have integrated real-time malware protection, with NordVPN becoming the first VPN to receive certification as a reliable anti-phishing tool in 2024. Surfshark's Surfshark One package offers comprehensive real-time protection from viruses and malware. Other VPNs, such as Avira and CyberGhost, utilize shared infrastructures for antivirus capabilities, which can lead to delays in updates and inconsistent platform support. Microsoft Defender has improved significantly, blocking 95.5% of live threats according to AV-Comparatives, while Apple employs multiple defenses in macOS, including Gatekeeper and XProtect, to manage malware threats. Avast Free Antivirus has achieved a perfect 100% block rate in recent testing but comes with limitations compared to paid antivirus suites like Norton 360 Deluxe and Bitdefender Total Security, which offer additional features such as password managers and identity monitoring. A layered approach to digital security, combining a VPN, free antivirus, and built-in OS-level security, is recommended for effective protection. Relying solely on one layer leaves potential gaps, as a VPN cannot detect existing malware, and free antivirus solutions may lack advanced features. Users managing sensitive data or frequent financial transactions should consider investing in premium antivirus suites for enhanced security.

How to check if your Android phone is still getting security updates

Smartphones may not receive crucial security updates, leaving them vulnerable to threats despite appearing to function well. Users can check their device's security status by navigating to Settings > About Phone to see the last security patch date. If it exceeds three to six months, the device may be nearing its support cutoff. Google Play system updates can also enhance security and should be checked via the Play Store. Manufacturers typically do not publicize end-of-life dates, but resources like endoflife.date can help users find this information. For example, the Samsung Galaxy S26 FE will receive updates until September 2033, while the Google Pixel 6 Pro will stop receiving support in October 2026. Google offers seven years of updates for Pixel 8 and newer models, while Samsung provides up to seven years for Galaxy S24 and Z Fold/Flip6 models. OnePlus offers four years of OS updates and up to six years of security patches. The European Union mandates a minimum of five years of software updates for new smartphones sold within the region starting June 2025. If a phone stops receiving updates, users should enable automatic app updates, avoid unverified apps, use two-factor authentication, back up data, and be cautious with public Wi-Fi. If the last security patch is over six months old or the device has surpassed its support cutoff, upgrading to a newer model is advisable.

Lime3DS Setup Guide: Play Pokémon on Android [2026]

- Nintendo’s 2024 legal action against Tropic Haze, the team behind the Yuzu Switch emulator, ended with a $**.4 million settlement** and the shutdown of Yuzu. - Lime3DS rose out of the shutdown of Yuzu and Citra as a community-maintained Citra fork, but development stopped in April 2025, leading to the creation of Azahar. - Azahar is the successor project to Lime3DS, but the Android package name was not updated, causing confusion. - Azahar is the default recommendation for 3DS emulation, consolidating the scattered forks that emerged after the shutdown of Yuzu and Citra. - Azahar requires specific system files from a real Nintendo 3DS console, and users must dump their own game files legally.

Why Endpoint Detection and Response Is No Longer Optional

Traditional antivirus software relies on a signature-based model that compares files against a database of known malware, which limits its effectiveness against modern threats. Cybercriminals have adapted by using polymorphic malware and fileless techniques that evade detection. Endpoint Detection and Response (EDR) continuously monitors device activities, tracking process activity, network connections, and file changes to detect behavioral patterns indicative of attacks. EDR also enables rapid response actions, such as isolating affected devices and terminating malicious processes. Small and medium businesses are increasingly targeted by attackers who exploit the limitations of traditional antivirus solutions. Relying solely on antivirus software creates vulnerabilities, making it essential for organizations to incorporate EDR for enhanced security.

The Evolution of Endpoint Security: Why EDR Represents a Fundamental Shift From Traditional Antivirus

Organizations that rely on technology face evolving cyber threats that traditional antivirus software struggles to address. Traditional antivirus detects known malware through signature matching but is limited in its ability to catch new or modified threats. Modern cyberattacks utilize techniques like polymorphic malware and fileless attacks to evade detection. Endpoint Detection and Response (EDR) tools have emerged as a solution, focusing on analyzing behavior rather than matching known threats. EDR continuously monitors endpoints, collects data on system activities, and uses behavioral analysis to identify suspicious actions. This allows for real-time responses to threats, such as isolating affected devices or rolling back changes made by ransomware. EDR is essential for all organizations, including small businesses, which are often targeted by attackers. It should be part of a broader security strategy that includes traditional antivirus, regular updates, employee training, access controls, and backups. When considering EDR options, businesses should prioritize response speed, visibility, reporting capabilities, and integration with existing IT support.

The Fault Line Spreads: Azure’s September CVE Cluster Now Covers PostgreSQL and Billing

Two newly identified Critical CVEs have expanded Microsoft's September identity infrastructure vulnerabilities to over ten verified weaknesses across more than ten distinct services. The Azure Database for PostgreSQL is vulnerable to CVE-2026-85878, an Improper Authorization flaw (CWE-285) with a CVSS score of 9.9. Azure Billing is impacted by CVE-2026-62874, which presents an Insufficient Data Authenticity Verification issue (CWE-345) with a CVSS score of 10.0. Both vulnerabilities were disclosed on September 18 and validated by Tenable and MITRE. CVE-2026-85878 allows an authorized attacker to elevate privileges over the network with minimal complexity, while CVE-2026-62874 requires no authentication, enabling unauthenticated attackers to jeopardize financial integrity. The vulnerability cluster first emerged during the Patch Tuesday cycles on September 3 and September 8, with initial reports highlighting critical flaws in core services. Other September disclosures include CVE-2026-83711 (Azure AD B2C, CVSS 10.0), CVE-2026-70352 (Azure AI Language, CVSS 10.0), CVE-2026-83941 (Entra ID, CVSS 9.9), CVE-2026-62916 (Entra ID, CVSS 9.1), CVE-2026-69857 (Azure Cosmos DB, CVSS 8.5), and CVE-2026-69854 (Spring Cloud Azure, CVSS 9.0). Activity heightened between September 17 and 18 with the introduction of CVE-2026-77903 (Microsoft Dataverse, CVSS 9.0) and CVE-2026-69843 (Microsoft Fabric, CVSS 10.0). The attack surface has broadened from authentication concerns to encompass trust in AI endpoints, data storage locations, and billing verification processes. Seven out of the ten vulnerabilities are unauthenticated, and all issues were addressed through server-side fixes by Microsoft. The extensive range of affected services suggests these vulnerabilities indicate a shared architectural dependency on authentication logic.

Windows 11’s driver signature requirement is one of the best anti-consumer security features out there

Windows 11 requires drivers to be digitally signed, a policy aimed at enhancing security by preventing unauthorized code from executing at the kernel level. This requirement, which began with Windows Vista and became mandatory with Windows 10, version 1607, has tightened over the years, especially with the introduction of UEFI Secure Boot and TPM in Windows 11. While this enforcement protects against malware and supports anti-cheat systems in gaming, it limits user autonomy and imposes significant challenges for developers, particularly those working on smaller projects. In contrast, Linux allows users more freedom to modify their systems, though this flexibility can compromise security.

‘Decades-old’ bugs found affecting Windows, Android, macOS and Linux — but the OS makers don’t see it as a big deal

Researchers at Graz University of Technology discovered significant vulnerabilities in the file-notification subsystems of major operating systems: Linux, Windows, macOS, and Android. These flaws, present for decades, allow side-channel attacks that can infer sensitive information like keystrokes and visited websites. The vulnerabilities are rooted in components such as inotify (Linux, since 2005), FileObserver (Android, since 2008), ReadDirectoryChangesW (Windows, since 2000), and FSEvents (macOS, since 2007). Unprivileged users can exploit these subsystems to observe file events, potentially leading to keystroke timing attacks and credential theft. While Linux has implemented partial mitigations (CVE-2025-68788), Microsoft and Apple have acknowledged the issues but have not provided substantial patches.
